Other factors to be considered when selecting and buying a stainless steel double suction pump:

1, the structure of the pump has an impact on the size of the pump house, the structure of the pump house and the layout of the pump room, so it is very important to the cost of the pumping station. For example, when the water source is very low, a vertical pump can be used to reduce the area of the pump room and reduce the cost when it is necessary to build a very deep pumping station. For example, a single suction vertical joint pump and a double suction horizontal joint pump in the station suction, pressure water pipeline layout is very different.

2, the normal water absorption of the pump should be guaranteed. In order to reduce the depth of the pumping station and reduce the cost of the project, the vacuum height of the pump should be fully utilized on the premise of ensuring no cavitation. At the same time, the height difference of each pump in the pumping station is too large, which causes the uneven depth of the foundation of each pump or the depth of the whole pumping station. Sanitary pump

3, the high efficiency water pump should be selected. If the large pump is chosen as much as possible, because the general large pump is more efficient than the small pump.

4, according to the different requirements for the reliability of water supply water supply, standby pump selection of a certain number, in order to meet the requirements in the case of accident in the water: not allowed to reduce water supply conditions (such as blast furnace and furnace workshop of metallurgical plant water supply), should have two sets of back-up machine group allows a short period of time to reduce the supply; under the condition of the standby pump only accident to ensure the supply of water; a short period of time to allow interruption of water supply, can only set a standby pump. The pump station in the urban water supply system is usually set up with only one spare pump. Usually the type of the spare pump can be the same as the largest working pump in the pump station. If the water supply system has enough height of the highland pool or water tower, it can partly or completely replace the pump station for short time water supply. Then the pump station can not use the pump, and only store a standby unit in the warehouse.

The spare pump, like other working pumps, should be in a state that can be started at any time.
